RTOG TISSUE REPOSITORYRadiation Therapy Oncology Group


H e slides l.jpg
H & E SLIDES

  • Stained tissue on glass slide.

  • Required for every case entered on a protocol for central review.


H e slides3 l.jpg

RESOLUTION

Re-cuts

Must have adequate tissue to show tumor.

PROBLEM

Pathology departments tend to be possessive of H&E slides.

H&E SLIDES


Paraffin blocks l.jpg
PARAFFIN BLOCKS

  • The manner in which biopsies are preserved.

  • Verify the block/blocks submitted includes a portion of the tumor used for diagnosis.

  • Required on most protocols.

PARAFFINBLOCKS

  • PROBLEM

  • Pathology departments tend to be possessive of paraffin blocks.


Plug samples l.jpg
PLUGSAMPLES

  • method uses derm needle to remove selected tumor area from paraffin block.


Plug samples7 l.jpg
PLUGSAMPLES

  • Request a Specimen Plug Kit.

  • Kit contains shipping tube and derm needle.


Plug samples8 l.jpg
PLUGSAMPLES

  • Ask pathologist to select tumor area.

  • Use the derm needle to punch the selected area from the specimen block.


Plug samples9 l.jpg
PLUGSAMPLES

  • Label needle with specimen ID.

  • Place derm needle into specimen shipping tube, without removing specimen from needle.

PLUGSAMPLES

  • Allows your pathology department to keep their original block, while submitting a tissue sample to us for banking.


Disadvantages of unstained slides l.jpg
DISADVANTAGES OF UNSTAINED SLIDES

  • Easily broken during shipment

  • Slides become negative for antibody detection in a short time

  • Difficult to store

  • Limited amount for staining

  • Cannot make tissue arrays from slides


Advantages of paraffin blocks l.jpg
ADVANTAGES OF PARAFFIN BLOCKS

  • Easy to store, no freezer necessary

  • Hundreds of samples are possible

  • Not broken in shipping

  • Antibodies are preserved

  • Tissue Microarrays are made from paraffin blocks


Tissue arrays l.jpg
TISSUEARRAYS

  • Allows a pathologist to look at many different tumor sections at once.

  • Helpful in finding common markers in hundreds of patients using only 1 slide, instead of hundreds of slides.


Tissue arrays14 l.jpg
TISSUEARRAYS

  • Core sample removed from specimen block.

  • Inserted into blank paraffin block.

  • Repeated until block is filled with rows of specimens, each representing a different case.


Tissue arrays15 l.jpg
TISSUEARRAYS

  • Grid chart used for documenting the specific location of each specimen.


Tissue arrays16 l.jpg
TISSUEARRAYS

  • Sections are cut from array block, and placed on glass slides.

  • Slides stained for pathologist review.


Pathology l.jpg

Share letter written by Dr. Hammond to announce the funding of the tissue repository by the NCI.

Explain that patient is participating in research study and has given written permission.

PATHOLOGY


Reimbursement l.jpg
REIMBURSEMENT of the tissue repository by the NCI.

Only offered for submissions which can be used for more than current study.

  • $200 Block / blocks submitted with tumor.

  • $200 Plug sample from the block, must contain tumor

  • $300 Blood, Serum, complex materials.

  • No reimbursement for H&E only submissions.


Submission requirements l.jpg
SUBMISSION REQUIREMENTS of the tissue repository by the NCI.

  • TISSUE (H&E, blocks, plug samples).

    One or all may be required per protocol.

  • Pathology Report.

    Always required.

  • RTOG Pathology Submission Form.

    Always required when tissue is being submitted.


Pathology submission form l.jpg
PATHOLOGY of the tissue repository by the NCI.SUBMISSIONFORM

  • MUST check appropriate box on submission form to specify level of patient consent.

  • Do not send me copy of patients consent.


Outside hospitals and laboratories l.jpg
OUTSIDE HOSPITALS AND LABORATORIES of the tissue repository by the NCI.

  • Make sure they understand importance of including paperwork with the pathology material.

PLEASE GO OUT OF YOUR WAY TO MAKE SURE THAT I RECEIVE EVERYTHING NECESSARY TO PROCESS YOUR PATHOLOGY MATERIAL!


What happens to tissue submissions l.jpg
WHAT HAPPENS TO TISSUE SUBMISSIONS EVERYTHING NECESSARY TO PROCESS YOUR PATHOLOGY MATERIAL!

  • Every piece of paper, every slide and every block is marked with protocol and case number.

  • Logged on sheet faxed to RTOG Headquarters.

  • Receipt information entered on calendar.

  • Send copies of paperwork which is put in patients file.

  • Tissue is filed until sent to pathologist or for future study.


Sending tissue to pathologist l.jpg
SENDING TISSUE TO PATHOLOGIST EVERYTHING NECESSARY TO PROCESS YOUR PATHOLOGY MATERIAL!

  • Periodically or when requested, material is sent to pathologist for central review or for a research study.

  • I am responsible to collect and send the following material:

    • Slides

    • Pathology report

    • Review form


Database l.jpg
DATABASE EVERYTHING NECESSARY TO PROCESS YOUR PATHOLOGY MATERIAL!

  • Our database allows us to account for disclosure of all information.


Rtog tissue repository l.jpg
RTOG TISSUE REPOSITORY EVERYTHING NECESSARY TO PROCESS YOUR PATHOLOGY MATERIAL!

  • A great resource for even more studies in the future.

  • To date the tissue bank has currently collected:

    • 17,251 Cases

    • 51,410 H & E’s

    • 16,360 Blocks
